Registering for the MB-500 exam costs $165 USD (varies by country) at the official rate, and you need 700/1000 to pass. Bear in mind that an unsuccessful attempt is not discounted the second time around — a retake is charged at the full fee again. That is why experienced candidates test themselves with the 431 practice questions from Actual4Dumps until their results are consistently strong before spending money on the real thing.
Yes, and we encourage it. A free PDF demo of the MB-500 questions is available so you can evaluate the quality and layout before buying. After purchase, your material stays current with 365 days of free updates — and if that period ever expires, you can extend the update service at a 50% discount through your member zone.
Registration is handled through the vendor's official channels:
As for how you will sit it, the MB-500 exam is offered Online proctored or test center (Pearson VUE) — pick the option that fits your situation during booking.
You will face 40-60 questions within a time allowance of 120 minutes. Raw numbers aside, the real skill is pacing: candidates who run out of time usually spent too long on early questions. Our advice is to set a mental per-question budget, skip and revisit anything that stalls you, and complete at least two full timed runs in the Actual4Dumps test engine before the real appointment so the clock never rattles you.
Both situations are covered. Take the corresponding MB-500 exam within 60 days of purchase without passing, and you may claim a full refund under our 100% Money Back Guarantee: submit a scanned exam enrollment slip plus the official Score Report PDF within 2 days of your exam date, and we finish processing within 7 days. The conditions are strict — an exam taken within 3 days of purchase does not qualify, the candidate's name must match the payer's, and free materials or expired orders are excluded. Would you rather keep studying? Swap the order for two other exam products of equal value free of charge while keeping updates on your original purchase. As for delivery, it is immediate: files unlock for download the moment payment clears, a copy reaches your mailbox within a minute, and there is no cap on how many computers you install it on — if 2 hours pass with nothing received, contact our support team.
Passing the MB-500 exam earns you the Microsoft Certified: Dynamics 365 Finance and Operations Apps Developer Associate certification, a Associate-level credential. It is the vendor's official proof that your skills meet the standard employers look for, and it regularly appears as a requirement in job postings. The certification also relates to Microsoft Dynamics 365 Finance and Operations Apps Developer Associate, Microsoft Dynamics 365 Core Finance and Operations Apps (MB-300), so it can anchor a broader certification plan rather than stand alone.
No mandatory prerequisites; recommended experience with Dynamics 365 Finance and Operations and MB-300 (Core Finance and Operations Apps) Because vendors revise their eligibility rules from time to time, treat this as a starting point and verify the latest requirements on the official exam page — see the official MB-500 exam outline before you commit to a test date.
The vendor organizes the Microsoft Dynamics 365: Finance and Operations Apps Developer blueprint into 5 domains, led by Implement data management solutions, Implement security and optimize performance, Design and develop AOT objects. Every domain contains further subtopics, and the weighting tells you where your study hours pay off most — the full outline above has the complete picture, so review it before building your study plan.
